You can also use the utility methods of Tx_Extbase_Utility_ObjectAccess. 
Those already handle arrays vs objects, find the correct getters and 
won't pose fatal errors if a property does not exist.

But apart from that:
@Roland do you have a more concrete example? Mostly it makes more sense 
to move such logic to your domain model. See also [1]
